Field Spraying Nozzle Output with Liquid Fertilizers

The sprayer is equipped with a spraying computer as standard. The section entitled "Operation of the spraying computer" describes the settings of the nozzle output when working with liquid fertilizers. If the computer works with a pressure sensor, the density correction factor must be programmed and activated. If the computer works with a flow sensor, no correction is necessary for the application rate control, but necessary for displaying the correct (calculated) liquid pressure.

In the case of manual spraying, the spraying pressure must be adjusted as described in "Adjusting the nozzle output" in this section. The resulting spraying pressure must however be multiplied by the density of the liquid. To this end, first weigh 1 liter to determine the density and next multiply the pressure by this value.

The tables give the output of the 3-hole & 7-hole Streamjet fertilizer nozzles
